Flowers that bloom in different months is an example of temporal isolaton.
What is temporal isolation?Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.
Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.

In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:
Answer:
Nothing
Explanation:
A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.

On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the Sahara desert. After observing it carefully you determine that it is not an autotroph, it is multicellular, and it does not contain any chitin. What is the best classification for it
Answer:
Animalia
Explanation:
A multicellular organism is an organism composed of two or more cells. Multicellular organisms include animals (i.e., organisms from kingdom Animalia), plants, and most fungi. Moreover, an autotroph is a living organism that can produce its own food by using materials from inorganic sources (e.g., water, carbon dioxide, etc); whereas a heterotroph is an organism that cannot produce its own food and thereby needs to eat other organisms, like plants or animals, to survive. Multicellular autotrophs are typically plants; whereas multicellular heterotrophs include all animals, fungi and some parasitic plants. Finally, chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is found in the cell wall of fungi, as well as in the exoskeleton of some animal groups such as, for example, insects, crustaceans, etc.

Why making anti-viral medicines is harder than making anti-bacterial medicines ?
Also Is Virus a living parasites?
Answer:
Making anti-viral drugs is more difficult than making anti-bacterial medicines because viruses have very few biochemical mechanisms of their own. They make use of host machinery which replicates. So it is very much difficult to find the targets where these drugs get interfered by not making any harm to the host. Thus, it is not easy to design an antiviral drug with high safety and effectiveness.
Explanation:
And i would say virus is a parasites but not a living parasite according to md
Answer:
Because antivirals can damage host cells where the viruses reside.
I hope this helps
all viruses are obligate parasites,that is they lack metabolic machinery of their own to generate energy or to synthesize proteins,so they depend on host cells to carry out these vital functions...

For example, when people began chopping down trees and making settlements in South America, fire ants started to move north in search for new homes. Eventually, they've became a huge problem to North America due to North America having no natural predators capable of eating these violent ants.
Answer:
Por ejemplo, cuando la gente comenzó a talar árboles y hacer asentamientos en América del Sur, las hormigas rojas comenzaron a moverse hacia el norte en busca de nuevos hogares. Con el tiempo, se han convertido en un gran problema para América del Norte debido a que América del Norte no tiene depredadores naturales capaces de comerse estas violentas hormigas.

Which of these is the main cause of habitat fragmentation? O A. Reduction in genetic diversity O B. Migration of mammal species O C. Demand for land use O D. Extinction of bird species
Answer:
C. Demand for land use
Explanation:
Habitat fragmentation usually occurs because of human activities such as new roads, parking lots, and housing developments. Organisms need their specific habitat for survival, and fragmentation is a leading threat to many terrestrial animals.

There is a famous psychology experiment where people sit in classroom in such a way that the person on either side of you can't hear what you say. This works best with more than 20 people.
The first person composes a sentence that has 3 facts in it. He whispers it to the second person who relays it to the third until the last person is told. The point of the experiment is to show that the last person isn't normally able to correctly repeat the 3 facts. In fact, most often what is given is quite mixed up and incorrect.
That's what's wrong with eye witness accounts. You can be certain of what you saw. You can also get it all mixed up.

Individuals with a mutation in the gene for apolipoprotein B-100 produce very low levels of this protein, which is a component of LDL. How would accumulation of fat in the liver be affected and would this result in hypercholesterolemia or hypercholesterolemia
Answer:
Fats would accumulate in the liver and the individual would show hypocholesterolemia
Explanation:
Familial hypercholesterolemia is a genetic disorder caused by a reduction and/or defect in the low-density lipoprotein (LDL) receptor. Moreover, apolipoprotein B is the unique protein component of LDL, which plays a critical role in lipid metabolism by binding the LDL receptor. Familial defective apolipoprotein B-100 refers to an inherited disorder associated with mutations of the apolipoprotein B-100 that leads to moderate or severe cases of hypercholesterolemia. Mutations in apolipoprotein B-100 are associated with a reduction in the binding capacity of LDL to the LDL receptor, thereby leading to hypercholesterolemia.

6. The first tree used to divide the dinosaur into two separate groups are the structure of their hips. What are the two groups and what do the group names mean?
The two groups are Tyrannosaurus Ornithomimus and Tyrannosaurus Coelophysis which are different from one another in shape and body structure.
The word Ornithomimus means ''bird mimic,” because it resembles the bird i.e. they are toothless and had beaklike jaws while on the other hand, Coelophysis means 'hollow form' and the specie has hollow limb bones that makes Coelophysis is a lightly body dinosaur that make it a fast hunter.

If new genetic variation in the experimental populations arose solely by spontaneous mutations, then the most effective process for subsequently increasing the prevalence of the beneficial mutations in the population over the course of generations is
Answer:
binary fission
Explanation:
Binary fission is the main type of reproduction of prokaryotic organisms. In binary fission, the prokaryotic cell first duplicates its DNA and then divides into two cells, each one receiving one complete DNA molecule. Since binary fission is a type of asexual reproduction, this process increases the prevalence of beneficial mutations in a bacterial population. Moreover, transduction refers to the process by which a virus transfers genetic information from one bacterium to another bacterium. Conjugation is also a sexual mode of transfer of DNA from a donor (F+) to a recipient (F−) bacterial cell by direct cell-to-cell contact. Finally, transformation refers to the transfer of genetic material by which bacteria take up exogenous DNA from the environment and integrate it in their genomes.
